Neurodiagnostics

North Shore Medical Center offers several types of neurodiagnostic tests, available on an outpatient and inpatient basis. Our technologists record electrical activity from the brain and nervous system using a computer and the data is then interpreted by a group of specially trained neurologists from Essex Neurological. The results are given to your primary care physician, who shares them with you during a follow-up visit.

Neurodiagnostic Tests at NSMC Union Hospital

EEGs

Electroencephalograms are given when your physician wants to evaluate a myriad of different neurological problems, from common headaches and dizziness to seizure disorders, strokes, syncope, dementia and degenerative diseases. The EEG is also used to determine organic causes for psychiatric symptoms. In addition the EEG is performed during carotid artery surgery to evaluate cortical functioning and in the evaluation of irreversible brain death (this is for inpatients only.)
